Of the 7 ports we visit on this cruise around the British Isles,  Liverpool has never been on my "must-see" short list.  In Ireland I was excited to visit Dublin because  of my interest in its great literary history. In Scotland, I am looking forward to going back to Edinburgh partly for sentimental reasons - a wonderful visit there with my then-fiance more than 40 years ago; and also because of the spectacular city-scape with Edinburgh Castle looming over the town. Glasgow holds family interest because that's where one of my grandmothers came from.   But Liverpool to me evoked images of grey buildings under grey skies, and apart from the fact that it was the birthplace of the Beatles, I knew very little about it.
